I\'m not sure I get your point entirely, so please, correct me if I mistake...
In my mind, one should not use words one does not understand to all extents, let alone such a word merely because its fashionable to do so; its a mockery to the beautiful language in which communicate... But the term \"n00b\" doesn\'t merely apply to one\'s English usage (\"1337-speak\" being the most obvious personification); no, I use the term \"n00b\" to define someone who is actively obnoxious, annoying, and/or harassing. Strangly (or perhaps not), those \"1337-speakers\" tend to fill this role exclusively, and therefore, \"n00b\" is a convieniant label.
Interestingly, in my long online gaming career, the term \"newb\" seems to be more offensive than any other. So this is generally retired from my vocabulary, especially when interacting with a newbie.
On another note, I believe I may have been the one to introduce Draklar to the term; wheter this was a Good Thing, or a Bad Thing, I\'m uncertain...
